If you’ve ever wrapped up a romp in the hay with shaky legs, you’re probably wondering why. While everyone’s body responds to orgasms differently, shaking and pelvic cramping after reaching orgasm can happen to many women.
To understand why you might have to cramp or shake, you first have to understand how an orgasm affects our bodies. During orgasm, you will experience myotonia, which is muscle contraction or tension that affects most of the muscles in your body. There’s a lot of tension built up around your muscles during orgasm, and when you relax those muscles after all the action, your legs might shake.
If you have pelvic cramping after you’ve orgasmed, it’s probably caused by a release of oxytocin, known as the cuddle or love hormone. Because of this hormone, you’ll have some uterine contractions and myotonia, which can cause cramping after orgasm.
In general, a little shaking or pelvic cramping after sex is normal and you shouldn’t worry. Most people notice a sense of well-being and a sense of peace that can last anywhere from 10 minutes to several hours after orgasm. During this period, you may feel the shaking or cramping sensations.
